Foreign body aspiration in dental clinics is the most common cause of respiratory emergencies. There are no reports on foreign body aspiration during dental treatment under stable general anesthesia because the patient neither has voluntary movements nor reflex actions. This is a case report on the fall of a prosthesis in the larynx, which occurs rarely under general anesthesia. During the try-in procedure, the prosthesis slid from the surgeon's hand and entered the retromylohyoid space, and while searching for it, it passed down the larynx to the endotracheal tube balloon, leading to a dangerous situation. The prosthesis was promptly removed using video-assisted laryngoscope and forceps, and the patient was discharged without any complications.

Unilateral pulmonary edema after minimally invasive cardiac surgery is a rare, but potentially life-threatening condition. However, the exact causes of unilateral pulmonary edema remain unclear. We experienced aggressive unilateral pulmonary edema followed by redo-resection of recurrent left atrial myxoma through a right mini-thoracotomy. Intraoperative veno-venous extracorporeal membrane oxygenation was applied after the termination of cardiopulmonary bypass, and separate mechanical ventilation using a double-lumen endotracheal tube was applied after surgery. The patient was successfully treated and discharged uneventfully.

A 14-year-old castrated male Persian cat presented with a 2-week history of respiratory difficulty. On physical examination, the patient showed intermittent open-mouth breathing and thoracic auscultation revealed wheezing. Thoracic radiographs revealed a narrowed upper airway and pulmonary infiltration. Computed tomography detected a mass occluding the lumen of the trachea at the level of the entrance to the thorax, a mass causing right main bronchus stenosis, and a nodule on the right caudal lung lobe. Bronchoalveolar lavage cytology tentatively diagnosed a carcinoma. Tracheal mass resection was performed through tracheostomy. Histopathology confirmed the presence of tracheobronchial carcinoma. The survival time after diagnosis was 10 months, during which time the cat underwent tracheostomy, debulking by endotracheal tube, and tracheal stent placement procedures in combination with toceranib phosphate adjuvant chemotherapy.

Background: Thoracotomy is the operation that produces the most postoperative pain, necessitating the highest requirements for postoperative analgesics. The common methods of treating postthoracotomy pain are the use of thoracic epidural analgesia, intemittent or continuous intercostal nerve blocks, intravenous narcotics and cryoanalgesia. We designed to assess the analgesic effect of epidural analgesia, cryoanalgesia and the combined analgesia in thoracic surgery. Methods: A prospective study was carried out in 59 patients undergoing elective thoracotomy for parenchymal disease. Patients were randomized into three groups: C (cryoanalgesia), CE (cryoanalgesia and thoracic epidural analgesia), E (epidural analgesia). All patients had standard anesthesia with endotracheal intubation using a double lumen endotracheal tube, and one-lung ventilation. Subjective pain relief was assessed on a visual analog scale. Analgesic requirements, complications and the degree of satisfaction were evaluated during the 7 days following surgery. Results: Subjective pain relief was significantly better in Group CE and Group E in comparison with Group C (P < 0.05). Cryoanalgesia provided a better pain score on the 6th and 7th POD than the early postoperative periods. Analgesic requirements were higher in Group C than in the Group CE and Group E during the first POD. The incidence of side effects was similar in Group CE and Group E. Conclusions: If we can reduce the concentration of fentanyl and local anesthetics in combined analgesia of epidural and cryoanalgesia, the disadvantages of each method would be overcome and would be a better method of postthoracotomy pain control.

Purpose: To investigate the differences in postoperative sore throat and hoarseness by adjustment of endotracheal tube cuff pressure (CP) during nitrous oxide ($N_2O$) and air anesthesia. Methods: A one-equivalent control group pretest-posttest design was used. Data were collected from August 8 to October 19, 2017 and analyzed using the independent t-test and repeated measures ANOVA. Eighty-four participants were enrolled and divided into three groups: 28 in the Control Group (CP adjusted every 30 minutes using $N_2O$), 28 in Experimental Group 1 (CP adjusted every 10 minutes using $N_2O$), and 28 in Experimental Group 2 (non-adjusted CP using air), all of whom underwent urologic, gynecologic, and orthopedic surgeries at the G University hospital. Sore throat was assessed using a numeric rating scale; hoarseness was evaluate using the Stout classification at 1, 6, and 24 hours after surgery. Results: Scores for sore throat and hoarseness were significantly different between the groups at each measurement time, and scores were consistently higher in the control group. During subsequent measurements, sore throat and hoarseness scores were significantly lower at 6 hours. Cuff pressure changed significantly using air anesthesia (${\chi}^2=10.41$, p=.015) up to 2 hours after induction. Severe sore throat and hoarseness was observed for up to 6 hours after surgery. Conclusion: Cuff pressure adjustment at short time intervals would be helpful in reducing postoperative sore throat and hoarseness. Nursing intervention focused on prevention of sore throat and hoarseness should be required up to 6 hours postoperatively in patients undergoing endotracheal intubation.

The efficacies of a supraglottic airway device (SGAD) and an endotracheal tube (ETT) in cats under general anesthesia with volume-controlled ventilation (VCV) were compared. Thirty healthy cats were randomly allocated for airway control using either an SGAD or an ETT. Five tidal volumes (6, 8, 10, 12, and 14 mL/kg) were randomly tested, and respiratory rates were adjusted to achieve a minute ventilation of 100 mL/kg/min. The dose of propofol necessary to insert the SGAD or ETT, the static respiratory pressure, leakage during VCV, and end tidal CO₂ (ETCO₂) were recorded. Dosages of propofol and static respiratory measurements for the SGAD and ETT groups were compared using a t-test. The distribution of leakages and hypercapnia (ETCO₂ > 45 mmHg) were compared using Fisher's exact test. A significance level of p < 0.05 was established. No significant difference in dose of propofol was observed between the SGAD and ETT groups (7.1 ± 1.0, 7.3 ± 1.7 mg/kg; p = 0.55). Static resistance pressure of the SGAD (22.0 ± 8.1 cmH₂O/L/sec) was significantly lower than that of the ETT (36.6 ± 12.9 cmH₂O/L/sec; p < 0.01). Of the 75 trials, leakage was more frequent when using an SGAD (8 events) than when using an ETT (1 event; p = 0.03). Hypercapnia occurred more frequently with SGAD (18 events) than with ETT (3 events; p < 0.01). Although intubation with an ETT is the gold standard in small animal anesthesia, the use of an SGAD can reduce airway resistance and the work of breathing. Nonetheless, SGAD had more dead space and the tidal volume for VCV needs adjustment.

Purpose : The incidence of mortality associated with respiratory difficulties is decreasing nowadays contributed to the development of neonatology. However, complications associated with mechanical ventilator are increasing. This study is to determine clinical manifestations, diagnositc availability of the endotracheal tip culture in patients with Ventilator-Associated Pneumonia(VAP) in neonatal intensive care unit(NICU). Methods : A retrospective analysis of 50 neonates who were admitted to the NICU of Kangnam Sacred Heart Hospital and had given mechanical ventilator from 1 January 2000 to 30 June 2003. VAP group defined as neonates who had pneumonia with mechanical ventilation longer than 48 hours. They were classified into VAP group(n=13) and control group (n=37) and the prevalence, microorganisms cultured from the endotracheal tube tip and risk factors were investigated. Results : The prevalence of VAP was 26.0%(n=13) and the most dominant microorganism cultured in our NICU was methicillin-resistant coagulase negative staphylococcus(MR-CNS) in 4 cases. Other microorganisms were Pseudomonas, Enterobacter, methicillin-resistant Staphylococcus aureus(MRSA) and Klebsiella. Gestational age, birth weight, Apgar score, respiratory distress syndrome, retinopathy of prematurity, bronchopulmonary dysplasia, sepsis, renal failure, pulmonary hemorrhage, pneumothorax were not different significantly between two groups except intraventricular hemorrhage(P<0.001) and patent ductus arteriosus(P<0.05). Duration of hospital stay and mortality rate were also not different significantly. Conclusion : VAP occurred at a significant rate among mechanically ventilated NICU patients. Despite of limitation of encotracheal tip culture, the most common microorganism was MR-CNS. We should be aware of occurrence of VAP in NICU neonate who were with mechanical ventilator and should treat with great care.

Background The indications for surgical airway management in patients with Robin sequence (RS) and severe airway obstruction have not been well defined. While certain patients with RS clearly require surgical airway intervention and other patients just as clearly can be managed with conservative measures alone, a significant proportion of patients with RS present with a more confusing and ambiguous clinical course. The purpose of this study was to describe the clinical features and objective findings of patients with RS whose airways were successfully managed without surgical intervention. Methods The authors retrospectively reviewed the medical charts of infants with RS evaluated for potential surgical airway management between 1994 and 2014. Patients who were successfully managed without surgical intervention were included. Patient demographics, nutritional and respiratory status, laboratory values, and polysomnography (PSG) findings were recorded. Results Thirty-two infants met the inclusion criteria. The average hospital stay was 16.8 days (range, 5-70 days). Oxygen desaturation (<70% by pulse oximetry) occurred in the majority of patients and was managed with temporary oxygen supplementation by nasal cannula (59%) or endotracheal intubation (31%). Seventy-five percent of patients required a temporary nasogastric tube for nutritional support, and a gastrostomy tube placed was placed in 9%. All patients continued to gain weight following the implementation of these conservative measures. PSG data (n=26) demonstrated mild to moderate obstruction, a mean apneahypopnea index (AHI) of $19.2{\pm}5.3events/hour$, and an oxygen saturation level <90% during only 4% of the total sleep time. Conclusions Nonsurgical airway management was successful in patients who demonstrated consistent weight gain and mild to moderate obstruction on PSG, with a mean AHI of <20 events/hour.

Objective : This study aimed to assess the relationship between increased intracranial pressure (ICP) and mastoid effusions (ME). Methods : Between January 2015 and October 2018, patients who underwent intracranial surgery and had ICP monitoring catheters placed were enrolled. ICP was recorded hourly for at least 3 days. ME was determined by the emergence of opacification in mastoid air cells on follow-up brain imaging. C-reactive protein (CRP) levels, presence of endotracheal tube (ETT) and nasogastric tube (NGT), duration of intensive care unit (ICU) stay, duration of mechanical ventilator application, diagnosis, surgical modalities, and presence of sinusitis were recorded. Each factor's effect on the occurrence of ME was analyzed by binary logistic regression analyses. To analyze the independent effects of ICP as a predictor of ME a multivariable logistic regression analysis was performed. Results : Total of 61 (53%) out of 115 patients had ME. Among the patients who had unilateral brain lesions, 94% of subject (43/50) revealed the ipsilateral development of ME. ME developed at a mean of 11.1±6.2 days. The variables including mean ICP, peak ICP, age, trauma, CRP, ICU stays, application of mechanical ventilators and presence of ETT and NGT showed statistically significant difference between ME groups and non-ME groups in univariate analysis. Sex and the occurrence of sinusitis did not differ between two groups. Adding the ICP variables significantly improved the prediction of ME in multivariable logistic regression analysis. Conclusion : While multiple factors affect ME, this study demonstrates that ICP and ME are probably related. Further studies are needed to determine the mechanistic relationship between ICP and middle ear pressure.

Purpose: The purpose of this study was to identify the effects of cuff pressure on postoperative sore throat. Methods: Data were collected from January 4 through May 15, 2008. Among the 60 patients, 30 patients were randomly assigned to the control group and the rest to the experimental group. Initial cuff pressure of both groups was set at 20 $cmH_2O$. The experimental group was maintained at 20 $cmH_2O$ throughout the anesthesia, while the control group was not regulated further. Sore throat was assessed at postoperative 1, 24 and 72 hours. Data were analyzed using Mann-Whitney test and Spearman's rho coefficients. Results: Cuff pressure in control group increased from 20 to 43 $cmH_2O$ within 3 hours after induction. However, the experimental group showed that there was apparently a reduced rate of sore throat at postoperative 24 hours (p = .048), and 72 hours (p = .002) than in the control group. However, no outstanding differences between both groups at postoperative 1 hour (p = .081) were detected. The correlation between cuff pressure and sore throat was statistically significant ($r_s$ = .590, p < .001). Conclusion: We conclude that maintaining cuff pressure at 20 $cmH_2O$ could be an effective means to reduce sore throat in surgical patients with inhalation anesthesia.
